Yuav ua li cas txhim kho cov txuj ci tseem muaj peev xwm ua kom alumina?

Qhib Aluminatau dhau los ua cov cab kuj tseem ceeb thiab cov khoom siv catalyst yog cuam tshuam los ntawm ntau yam kev npaj ua si los ntawm cov qauv sib txawv thiab cov qauv tshuaj sib xyaw ua ke yog qhov tseem ceeb rau kev txhim kho nws daim ntawv thov Tus nqi .

1.}} Cov cheeb tsam tshwj xeeb

Qhov loj dua cov chaw tshwj xeeb, cov chaw kawm ntawv adsorption ntau ntxiv yog nce los ntawm kev tswj qhov muaj peev xwm los ntawm kev tswj qhov tseeb, precursor xaiv, thiab lwm yam.

2.}} pore cov qauv

• Kev faib tawm loj: Cov micropores yog tsim nyog rau me me molecule adsorption, thiab mesopores yog conducive rau loj Molecule Adsorption {}}

• Porosity: siab dav tuaj yeem ua kom muaj peev xwm ua tiav kev kos duab, tab sis muaj kev siv tshuab lub zog yuav tsum tau coj mus rau hauv tus account {}}

3. nto qaub ncaug tshuaj

• HYBOXYR cov ntsiab lus: cuam tshuam rau saum npoo polarity thiab adsorption exprity .

• Acidic / Cov Chaw Yooj Yim: tuaj yeem hloov kho thiab kho kom txhim kho qhov muaj peev xwm txhim kho ntawm cov khoom siv tshwj xeeb .

4. impurities thiab siv lead ua daim ntawv

Impurities yuav thaiv pores thiab txo kev ua tiav kev ua tau zoo; -Thaum muaj cov txiaj ntsig adsorption muaj zog dua -al₂o₃.

1.} Xaiv cov txheej txheem npaj

• Xaiv cov txiaj ntsig ua ntej: xws li pseudo-boehmite, txhuas gel, thiab lwm yam}}, uas cuam tshuam rau thaj tsam pawb thiab thaj chaw tshwj xeeb.

• Tswj cov kev xam xyuas kub: kev kub heev yuav ua rau Sintering thiab txo thaj chaw tshwj xeeb thaj tsam .

• Kho cov nag lossis daus lossis cov mob laus: cuam tshuam rau cov nplej loj thiab pore faib .

2. kev hloov kho deg

• acid / hauv paus kho: Kev kho mob nrog HCL, HMOHSH tuaj yeem nce cov pab pawg hydoxyl thiab txhim kho cov kev ua haujlwm tshaj tawm {{}

• Kev thauj khoom tiv thaiv: xws li impregnation ntawm cov hlau ions xws li Ag⁺ thiab Cu²⁺ los txhim kho cov kuab paug tshwj xeeb .

• Kev Hloov Kho Orgification: txhim kho hydrophobicity thiab yog tsim rau adsorption ntawm cov organic teeb meem .

3.}}} tswj tus qauv pore

• Qauv Txheej Txheem: Siv Surfactants lossis Polymer Templates los npaj cov kev txiav txim siab Mesoporous Alumina.

• Kev Kho Mob Hydrothermal: Txhim kho Pore txuas thiab txhim kho cov lus tshaj tawm adsorption .

4.}} optim် ua kom zoo siv

• Kho tus nqi pH: cuam tshuam rau tus nqi sib txawv, xws li thaum adsorbing fluoride ions, p p {} yog qhov zoo tshaj plaws.

• Txhim kho kev sib cuag tau zoo: Siv lub txaj fluolized lossis tsau txaj los ntawm txhim kho huab hwm loj .

• Txoj kev tsim kho tshiab: qhov kev kub siab tshaj plaws lossis cov kua qaub ua tau rov qab muaj peev xwm ua tiav lub neej thiab txuas ntxiv txoj kev pabcuam lub neej .

• Kev kho dej: Hloov khoQhib Aluminatuaj yeem tshem tawm cov kabmob uas muaj phom sij xws li fluorine thiab arsenic los ntawm dej .

• Cov roj kom qhuav: los ntawm kev hloov kho lub siab loj, kev tshaj tawm cov adsorption ntawm h₂o thiab coo tuaj yeem txhim kho .

• Cov cab kuj catalyst: thaj chaw tshwj xeeb thaj tsam thiab acidic cov chaw pab txhim kho catalytic kev ua si .
